Crocea likes to lay down???

Why does the crocea I have had for about 3 months constantly lay over its side? He never has looked that great seems to always gape too.

Help me figure this out. thanks
 
Can you post a pic? Also, what are your tank parameters. Where is the clam in the tank? I see you list 2 250W MH as lighting.
 
My lights just went out so I can't post a new pic. But my lighting is as mentioned 2 x 250 Iwasaki. In fact, I just bought new bulbs about two weeks ago.

Tank parameters:
PH 8.2
Calc/Alk 390/11dKH
temp 82-84 (summer)
nitrate/nitrites 0.0
PO3 0.0

I run a calc reactor
Tank is 2.5 years old
 
What is your clam on, rock or sand? Croceas like to be on rock, if you want it on the sand try putting a piece of rock under it and it should attach in a few days.

Croceas tend to gape more than any other clam, but three months is a little much. If the ckam is not attached to a piece of rock, that is probably it.

I have one who does the same thing. He is sitting on the bare bottom, on his side, and attached to the LR. Looks healthy and happy.
 
I have the clam attached to a piece of rock in the sand. The clam still rolls halfway on its side??? I have moved it twice in the three months. I will leave it alone for a while on its side.

Creeper: How long has yours been that way?

Thanks for the input.
 
I have 4 croeca in the sand bed that do the same thing- (for over a year) My best guess is they are doing what they want !! Lasy as a clam. it does not seem to hurt them. Any time I put them in the rockwork they"jump" out. I have just learned to live with it and adjust them every once in a while to my liking. Whose tank is it anyway?
 
It's probably the change in lighting. Your new bulbs have made a significant change in the lighting and your clam is squirming around to find its "happy place" with the new bulbs. This happens with all my clams, attached or in the sand, when I change lighting.

If you keep them in the sand, I'd still consider putting them on some LR or a clam shell. It will help protect the byssal gland from attack from worms, snails etc.
